Letters Patent No. 113,705, dated April 11, 1871.

IMPROVEMENT IN CA'RRIAGES.

The Schedule referred to in these Letters Patent and making past of thelame.

To al'l whom lit may concern:

Be it known that i, CHAUNCEY THoMas, of Boston, in the county of'Suffolk and State of Massachusetts, have invented Improvements inOarriages; and I do hereby declare that the following, taken inconnection with the drawing which accompanies and forms part of thisspecification, is a descriptiono my invention suicient to enable thoseskilled in the artvtopractice My invention relates to the constructionand arrangement of the carriage-body and spring-supporting mechanism .offour-wheeled vehicles, the invention as relates to the body havingparticular reference to the manner of uniting `a metal body toA a sunkenwood bottom, and as relates to the springs, having particular referenceto a provision for end movement of the rear parts of the springs ofside-spring carriages.

The invention consists in mounting. or supporting a carriage orwagon-body upon side springs, the rear end of' each vot which isprovided with au eye or runner that rests and slides upon a short rod,mounted in a stand, iixed upon the top'of the rear axle or axle-bed. Y

The invention also consists in a sheet-metal ,body,

having a sunken wood bottom united to the bottom l of the body sides bya anged connecting-plate, the upper flange of which extends over andrests upon an inwardly-turned iiange at the bottom of the body sides,(the edge of the plate-flange abutting against the inner surface of' thebody sides,) and the bottom flange of which extends inward and forms asupport for thewagon-bottom, the flange-plate being inclined or curvedbetween its top and bottom flanges.

The invention further consists in u-prights for supporting the crosspieces for the seat, fastened to the body by metal-strap pieces, whichare riveted upon the inner surfaces of the base-plate and to the innersurfaces of'i the uprights, so that the seat is supported withoutextending fastenings through the metal body sides,

The invention further consists in the manner `of making the corners ofthe iiange-plate where the end and side pieces are joined.

The drawing represents a carriage-body and springs embodying myimprovements.

A shows the body and springs in side elevation;

B is a section on the line x :1;

O is a plan of' the body and springs; and

D, a reversed plan of the body.

E F and Gr are detailsillustrating thc manner of forming the corners ofthe bottom sides.

H is a section (enlarged) showing the manner of` connecting the vertical.body sidesand the wood bot-' tom by the bottom side or flanged plate.

a denotes the body or body sides, preferably formed of one sheet ofmetal, bent to proper shape, or into boi: form, and having at the bottomof' each side an inwardly-turned lip or fiange, b.

c denotes the bottom, made of wood, and deepening from the ends towardthe center to form ample leg and foot room.

d denotes the bottom sides or the metal flangeplate that connects andunites the body` sides a and bottom b. y

This bottoni side piece is composed of end pieces e and side pieces f,connected together to form one frame. At the top of`v this bottom sideor frame, and all around it-,is an outwardly-projecting flange, g, theedge of which ts against the inner surface .of the hodysides, thisflange resting directly upon the body ila-nge or lip b, the two beingfastened together by suitable rivets or bolts 11..

From this flange g the bottom side or Harige-plate inclinesdowninwardly, (being preferably made with a swelling-curvedinnersurfane,) and at its bottom it has another and inwardly-projeotinghorizontal flange,

fi, extending all around its four sides, and upon this flange rests thebottom pieces b, cach piece b being chamf'ered or beveled at its edge,so that thenpper that the method of connection is such as to leave noopen joints or prominences or uneven edges.

To efect a neat and substantial connection of the side and end pieces ofthe bottom side frame, I outout the abutting ends of the strips beforebending them, as seen at E F, forming on one piece a tonguepiece, nl,that laps over and fits against and is riveted tothe inclined side oflthe other piece, the bottom edge of this tongue and the adjacent end ofthe flange of the same strip butting when' bent, the flange of the otherpiece extending under and being riveted to the first flange by a rivet,n.

The top fianges abut as seen at o, and the angle of the tongue 'm andthe side piece from which it springs is in line with the end 12 of theincline behind it.

To obviat the necessity of bolt-ing through the body sides (which wouldmar the finish oi' the body) to secure the seat-supports, I place eachvertical seatpost Ir against the inner surface-of the body side, as seenat B, and bolt them to metal-strap pieces s, which are bolted to andextend up from the bottom an eye-piece or runner, z, on the end of thespring.

Claims. Y

l. In combination with a met-al body, a, and wood bottom b, a connectingbottom side or frame, d, having a to'p ange, G, supported upon a flangeor anges, b,

projecting inwardly from the bottom o` the body sides a, and a bottomange, c', upon which the bottom strips arefsupported, substantially asshown and described.

2. In combination with the metal body' w, the seatposts placed againstthe inner surface of the opposite body sides, and riveted or bolted tovertical metalstrap pieces s, Whose lower ends are fastened to thebottom-sides frame d, substantially as shown and described.

of the bottom side pieces d, substantiallyas shown and described.

4. Side springs, tl1e rear ends of Which-have e'yepieces or runners z'sliding upon rods y, iixed in heads or Yplates x, on the rear axle oraxle-bed, sub` stantially as shown and described.
